Answer :

Double replacement reaction : It is a type of reaction in which a positive cation and a negative anion of the reactants react to give a new compound as  a product.

In this, A and C are the cations and B and D are the anions.

When one mole of potassium hydroxide react with the one mole of zinc chloride to give one mole of zinc hydroxide and 2 moles of potassium chloride.

The balanced chemical reaction is,

answer is a

explanation:

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
